To this end my invention consists in the construction and combination ofparts forming an automatic box assembling and nailing machinehereinafter more fully described and particularly stated in the claims,reference being had to the accompanying drawings, in which Figure 1 is aperspective view of a box assembling and nailing machine embodying mysaid invention, Fig. 2 a horizontal section but showing the table andrevolving parts principally in top plan, Fig. 3 a detail end elevationof the nail boxes and adjacent parts, Fig. 4 a detail view of thedriving gear showing a part of the operating devices and showing thedischarge mechanism in perspective, Fig. 5 a longitudinal sectional viewthrough nism, Fig. 6 a detailview of one of the supporting chairs in thereceiving hopper, Fig. 7, a detail viewshowing the nail picker baroperating mechanism, Fig. 8, a detail view illustrating portions of therotary table operating mechanism, Fig. 9, a detail view of the hopperposts25 and the adjacent parts, Fig. 10, a detail cross section throughthe hopper at station 54 and adjacent parts, Fig. 11, a detail view ofone side of one of the frame-holding chairs, Fig. 12, a detail view oftwo parts of the assembling head, Fig. 13, a detail view of the nailinghead and adjacent parts, and Fig. 14, a detail view of the cam foroperating the assembling head and nailing heads.

may be best adapted for the purpose and requires no special description.The nail boXes O and nailing mechanism form the subject matter of aseparate application and need not be particularly described herein. Thedescription will therefore be largely confined to the mechanism to whichthe improvements constituting the invention particularly relate.

In the drawing the numeral 5 represents the carrying table, hexagonal incontour, and mounted to revolve on a vertical shaft 6, which is a 'fixedportion of the machine frame being mounted in base A. On this carrier,at each of its six sides, a pair of chairs 7, 8, are mounted, each chairhaving a rib 9 fitting a groove 10 in the face of the carrier 5 wherebythe two chairs of a pair may be adjusted in a line tangent to the circleof motion of the table and be separated more or less to adapt them toframes of different sizes and yet remain parallel with the centralradius, as 11, of that side. Each chair has floors on two levels, thelower floor 12, being to receive the side pieces 13, which have thedove-tailed tenons attheir ends, and the upper floor 14 to receive theend pieces 15, which have the dovetailed mortises in their inner sides.The chairs are fitted to receive the end pieces 15 with about one thirtysecond of an inch freedom each way. They are fitted to receive sidepieces 13 with about the same lateral freedom and the chairs are to beadjusted on the table 5 to suit the length of the frame being assembled,the shoulders 16 of side pieces 13 meeting the faces 17 in thewhich theend pieces 15 rest, whereby the exact registry of the tenon with itsmortise is insured. Said faces 17 are recessed at their ends toaccommodate the dove-tailed tenons, as will be readilyunderstood.

A hopper for side piece 13 is preferably provided comprising two pairsof posts 19, grooved to receive by their tenons, two piles of f ramepieces 13, andsecured to brackets 20, each of which is provided with arib 21' j to engage a groove 23 in the edge of table 22, as shown inFig. 9, whereby these bIZLCk'.

ets are adjustable relative to the radial line 24. Two other pairs ofposts 25, are mounted'on brackets 26 to serve as hoppers to receivepiles of end pieces 15. These posts are provided each with a rib 27 toenter mortises in the pieces 15, also with backing ribs 28 to keep thepieces in engagement with the ribs 27, and these brackets are adjustablealong the edge of table 22 to correspond with the length of the sidepieces 13".

. Two more pairs of posts 2,9-are secured to a pair of brackets, whichare fitted and engage the table 22 like the brackets and 26. Said postsare shaped as corner grooves to receive a pile-of box ends or panels 31,

which rest on thin plates 82, that are attached to the brackets andlocated enough above the side 33 to permit one panel at a time to passover the said side. The rear chair '7 of each pair is provided withstuds 34 which project above the plane of the pieces 15, enough toengage one panel.

The table 5 is to be revolved step by step,

one sixth of a circle at each move by mechanismas follows: A crank 60 onone end of shaft B isconnected by a pitman 61 toa lever 62 which ispivoted at its lower end on a pivot 63 projecting from the base A. The

upper end of said lever 62 is bifurcated and has a head pivoted therein,the lower end of which engages on one side of a tapered wall inthe'bifurcation, holding said head when innormal position, in line with theeveigbut permitting it to tilt in the oppositedirection on its pivot 65.A latch 67 is "of Figs. 1and8. As the crank 60 revolves mounted on apivot 68' on a boss on an appropriate part 69 of the frame. Said latchis adapted to engage with a radial pin 70 projectingfrom one cornerofeach of the SD: sides of the carrier table. The operation will be bestunderstood by an examination itoperates said lever 62 back and forth.The forward motion being inthe direction 5 indicated by the arrows inFig. 8, the top of the head 64 will firststrike the inclined underfaceof the rear end of the latch'and lift itfree from engagement with thepin and at the same time carry said pin and the table forward one fullstroke, or to the position indicated by dotted lines in the right ofsaid figure. When this position is'reached, the 1 .7 of the next side ofthe carrier table will reach the notch in the latch and be engagedthereby, thus holdingthe carrier in position until forcibly advanced bythe next forward movement of said lever. On the return movement of saidlever, head 64 turns on ts pivot and passes under the latch and pin'freely, but as soon as it is past the weightof the lower end of the headcauses it to fall into normal operative position, as

shown in'who'le lines inlFig. 8.

The pressing together and nailing is done at station 55, the nailingmechanism being the subject of another application for a patent of evendate herewith. On arriving at station 56, the completed heads are raisedout of the chairs by the operation of levers 42, and lodged upon theinclined shelves A7, from which they slide into the delivery spout 53.

At every step of rotation of the carrier table 5, the function at eachstation is performed during the stop, excepting at 53, which is leftopen for free inspection of the work. 7
